What This Standard Means
What Students Need to Do
- Students understand that the equal sign means both sides have the same value. They decide whether addition and subtraction equations in varied forms are true or false.
What Mastery Looks Like
- The student recognizes 8 = 5 + 3 as true and 4 + 2 = 5 as false. The student compares both sides instead of treating the equal sign as an answer signal.
Common Misconceptions
- Students may think the equal sign means calculate what comes next. They may reject equations with one number on the left or operations on both sides.
How to Assess It
- Ask students to label 7 = 4 + 3, 5 + 2 = 4 + 4, and 9 - 2 = 3 + 4 as true or false and explain.

Ways to Teach It
Build both sides of equations with cubes on balance mats and check whether the quantities match.
Ask students to explain what the equal sign says in 6 = 2 + 4.
Play true-or-false equation sort using cards with totals placed on either side of the equal sign.
Compare two groups of classroom items and write an equation showing whether their totals are equal.
